SWPadnos: hey, is there any major advantage of a Mesanet 5i23 (400k spartan 3) over the 5i20 (200k spartan 2) in the near emc2 future?
I don't see one. what's the cost of the 5i23?
5i23 > 229
5i20 > 199
ok - not too much more money.
it could sure be made to work, but I don't think any of the guys have one
newer, faster, smaller, whiter and brighter?
sort of, until you look at the 5i22 ;)
but that's much more expensive (and 1.0 or 1.5M gates)
but that's lots more $
i want to put together 6 axis system.
then you really want a 5i22 - you can do 8 axes and still have 48 I/Os on one card
emc2 drivers yet? or soon?
the config loader already recognizes the 5i22 cards
but making an old-style driver for it wouldn't be a great use of time at this point
will it load the 5i20 code so i can use it now as a 5i20?
the bitfiles would be different, even for a config that just used 3 connectors
well, not being a vhdl programmer, i'm looking for a way to get started now and i have a 5i20 card already.
if i add another 5i20, i'm up to 8 axes.
ok - you can certainly use the 5i20 (or maybe even two) for now, I'm not sure when the newer stuff will be added
have you tried using two 5i20s in one machine?
no, not yet.
should that be a challange?
it should work up to 4 boards
shouldn't be, but I don't know that it's been tested yet
guess i'll find out. think i'll drive over to mesa and pick up another 5i20, unless someone has one they want to sell cheap.
I've got 3 that I can test with, but I'm not sure I want to sell them cheap :)
what do you think of their compact flash to ide adapters?
CF to IDE is commonplace
stuff the os and all onto a 4g cf unit?
a diskless system.
all swap file work in ram?
I configured a few machines that have no swap, using 8GB SSD drives
no swap? lots of read/writes?
they could easily use 4GB - there's that much left over, and these have all the development stuff on them
well, it's not running EMC per se - it's a HAL application, no X, read-only filesystem, etc.
in theory you should just copy the live cd iso to a CF
that sets up most you'll need
just had firefox poop. back on now.
maybe with a different partition for home
Office Max has a 4g on sale for $25, think i do that and see how it goes.
8g for $48.
alex_jone and SWPadnos, thanks for the info.
